Next cut more of the breakaway headers and female headers at the right sizes, 10pins and
8pins. You will always loose one pin when cutting the female headers, so don't worry about
it.
Now to ensure that the headers are properly aligned, screw the hex screw and the standoff
on bottom board. Place the female headers on button board with the male pins inserted.
Now place top board, screw with the standoff screw and finally, solder the headers to both
boards. Just like in the image below.
Unscrew the top spacer again and disconnect the two boards.
Place the four potentiometers to their respected places on the board. Push them well until
they
sit absolutely flat on the board
, but don’t solder them yet.
Next, place the mono jacks on the board and the switch.
